To all whom it may concern:

Be it knownV that I, CLEorHAs Roone'r'rn, of St. Sauveur, in the Province ot' Quebec, in the Dominion of Canada, have invented a certain new and useful Improvement in the Art of Manufacturing Laminated Stiffeners for Boots and Shoes, of which the following is a specification.

My invention relates to the manufacture of stiffeners composed of a number of layers or sheets of material at the different sides and placed one upon another.

The invention relates to` an improved method of molding and uniting the several layers; and it consists in subjecting the same, after they are. placed one upon another, to compression between a hard plate or surface upon one side and an elastic plate or surface upon the other, the material used being ordinarily a metallic plate anda plate or block of soft or elastic wood.

Figure l is a view of my improved stitfener with the top layer removed. Fig. 2 is alsection showing the layers of which the stiffener is composed. Fig. 3 is a view of a plate ofiron or other hard unyielding material used for pressing` the improved stiffener. Fig. 4 is a view of a plate ot' wood or other elastic material used for pressing the improved stiifener. Fig. 5 is a pile of plates ready for pressing.

` The `stiffener is composed of several pieces or layers ofleather or other material, the aggregate thickness of which is equal to the-thick- -ness required inthe stilfener, the individual pieces beingthereforecomparativelythin. The pieces or layers are also of various sizes, the smallest being placed inside between two ontside full-sized pieces.

The,stilfener illustrated in the drawings is composed of four layers or pieces of three different sizes,the external pieces, L L, being the full size ofthe stiti'ener, the two smaller ones,

VL and L2, being placed between them. When the layers or pieces are pasted and placed in their proper relative position they are pressed between two plates or blocks, one of which, I, has a hard andl unyielding surface, such as iron. The other, W, is of a softer and yielding material-such as pine, poplar, or other reasonably soft and elastic wood-apiece or sheet of cloth, C, being placed interveningly between the surfaces of the plate and the stiffener,

to facilitate the removalof thelatterafter pressing. The plates I and W, with the unlinished stitfeners between them, are then subjected to pressure in any suitable press, a number or pile, such as shown in Fig. 5, beingpressed simnltaneonsly.

The object of usinga hard and a softplate is that, after pressing, one side of the stiffener will be. quite tlat, while the other assumes a curved contour in consequence ofthe varying thickness produced by the various layers, the yielding surface of the soft plate being indented by the layers, thus producing a more even pressure over the whole surface,while with hard and unyielding surfaces alone the thickest parts only would be pressed. I find that iron and wood answers all practical purposes, respectively, fora non-yielding and a Iyielding' plate.

The latter, W, I bind with anv iron y hoop, h, to prevent their splitting under pressthat a stiffener of any thickness can be produced with its edges tapering down to the thickness of the two external layers, or, ifpreferred, to one layer, in which case one of them is made somewhat less in size. y

1t will also be observed that in this manner small pieces of material, which might otherwise go to waste, may be utilized for the smaller internal layers.

I find that a piece ot' cloth placed between the surfaces ofthe plates and the stiffeners to be pressed prevents their adherence to the plates after pressing, and that the cloth can be more conveniently separated from the plates and the pressed stit'teners from the cloth. The introduction of this cloth, although desirable, is not a necessary feature of the process.

The resultof myimproved method of manufacture is a well-shaped and well-consolidated stiffener, produced with comparatively little hand labor and partly out of waste materials.

I am aware that a stitfener has been composed of several layers otl material, and this I do not broadly claim.

I am also aware that the stiffeners consist- -ing cfa single sheet with chamfered edges have been folded by rubber-faced jaws around an anvil or last, and this I do notI claim, my invention relating to the treatment of the series IOO ofsheets or layers to reduce or bevel their shoes, the process of compressing and forming 15 A edges without the labor expense of scarng -thesame,consistinginplaeing thelainin one them; but l :upon,anotherrapplying a sheet of cloth to the What I do claim is outer surface of the body thus formed, and
